To all whom tt may concern:

Be it known that we, HENRY G. MGPIKE, J r., and HARRY B. HARLOW,citizens of the United States, residing at Alton, Illinois, haveinvented a certain new and useful Improvement in Paper-SlottingMachines, of which the following is a full, clear, and eX- actdescription, such as will enable others skilled in the artto which itappertains to make and use the same, reference being had to theaccompanying drawings, forming part of this specification, in which-Figure 1 is a perspective view of a cardboard slotting machine of ourimproved construction. Fig. 2 is an enlarged trans* verse section takenon the line 2-2 of Fig. 1. Fig. 3 is a detail section taken on the line3&3 of Fig. 2. Fig. 4 is a detail section taken on the line 1 -1 of Fig.2.

Our invention relates to a machine for slotting corrugated paper board,cardboard, thin veneer, and like material, used for the purpose offorming packing boxes and fillers adapted to inclose fragile articlesduring transportation or storage.

In packing small, fragile articles it is the practice to form a seriesof compartments or cells by arranging strips of corrugated paper board,or like material, at right angles to one another, and in order to do sothe strips of packing material must be uniformly slotted in order toproduce a structure having compartments or cells of uniform size, and wepropose to provide simple, inexpensive means whereby the strips ofcorrugated board, or like packing material, are uniformly cut orslotted.

To the above purposes, our invention con sists in certain novel featuresof construen tion and combination of parts hereinafter more fullydescribed and claimed.

In the construction of the machine shown, we employ a pair of sideframes 1, the front portions of which are connected by a rail 2, on topof which is arranged a longitudinally disposed rib 3. Formed on the rearportions of the frames 1 are bearings 4C, in which is arranged forrotation a shaft 5 driven in any suitable manner, and arranged on saidshaft 5 is a key or feather 6. A series of cardboard supports inthe formof rails 7 are arranged in pairs and extend from the rail 2 to the shaft5, the under sides of the forward ends of said rails being slotted, asdesignated by 8, in order to receive the rib 3.

Arranged between the forward ends of each pair of rails 7 is a fillerblock 9, and carried by the forward ends of said rails 7 is a bearingblock 10, which engages the front side of the rib 3. Passing through thelower portions of the forward ends of said rails 7 are set screws 11which bear against the block 10 and force the same toward the rib 3.

The construction just described provides for the adjustment of theforward ends of the pairs of rails 7 longitudinally upon the rail 2, andalso provides for the locking of said pairs of rails 7 after adjustment.

Fixed on top of the rails 7 are strips 12 of steel or hardened metal,the inner edges of which form cutting edges, which oppose the cuttingedges of the knives or critters which pass between the pairs of strips12 and pairs of rails 7.

Adjustably arranged on the rib 3 at one end of themachine, andpreferably the right hand end thereof, is a block 13 carrying arearwardly projecting vertically disposed plate 14, which forms a guideor gage against which the left hand end of the section of cardboardengages when said section is placed on the machine.

Blocks 15 are adjustably arranged on the rib 3 between the forward endsof the rails 7, and carried by said blocks are rearwardly projectingadjustable rods 16, the rear ends of which are bent upward to formfingers 17, which perform the function of gages and against which therear edge of the section of cardboard is positioned when placed on themachine.

The rear ends of the rails 7 are provided with integral lugs 1S whichencircle the shaft 5, and arranged to rotate in said lugs are collars 19which fit snugly upon and rotate with the shaft 5 by reason of the keyor feather 6.

Fitted on to the outer ends of the collars which hub is in the form of aring which ts snugly between the rear portions of the rails 7, andpassing through coinciding apertures.

formed through the collars 19 and the interposed hub 23 are rivets 24,or like fastening devices.

'By the construction just described, it will be noted` that the collars19, lugs 21 and hub 23 are rotated with the shaft 5 and bear in therings 18 formed on the rear ends of the brails 7.

Formed on or fixed to each of the hubs 23 is a cutter' arm 25 in theform of a plate of such thickness as to readily pass between the plates12. One edge of the cutter is provided witli a series of points 26having inclined cutting edges on either side of each point, forming azigzag cutting edge, and this edge-of the plate or cutter performs thecutting or slotting operation as it passes between said plates 12. Anynumber of cutters and corresponding pairs of rails 7 may be located onthe machine, and by loosening the set screws 11, the pairs of rails andcutters may be adjusted longitudinally and spaced the desired distancesapart.

In the operation of our improved machine, the shaft 5 is rotated in anysuitable manner, and the sections of cardboard, corrugated paper board,or veneer, are placed one at a time upon the pairs of rails, the lefthand end of each section bearing against the gage plate 1&1, and therear edge of said section bearing against the lingers 17. As the cutters2,5 pass between the plates 12 located on the pairs of rails 7, thesection of material will be slotted, said cutters making a shear cutthrough the material by reason of the points 26 on the edges of saidcutters, and thus uniform and clean edged slots are formed in thematerial. At the time the slotting operation is performed, the rear oneof the points of each knife iirst engages the cardboard, or likematerial, and in a measure clamps the same upon the supports withoutexerting any backward thrust on the material which is the case where theslotting device or cutter first engages against the rear edge of theVsection of material. The succeeding points pass through the material,and as the edges of the cutters between said points are inclinedrelative to the horizontal plane occupied by the strips 12, a shear cutis made through the material, and whichv manner of cuttingfcan'beaccomplishedwith an expenditure of little power.

A machine of our improved construct-ion is comparatively simple, isoperated with very little power, is readily adjusted, and very rapidlyperforms the work of slotting cardboard, corrugated paper board, andlike material, used for packing purposes.
